Description

The shaft seal for the gearbox is an essential component in concrete mixers, ensuring tightness around the drive shaft of the planetary gearbox. It operates under demanding conditions, such as the presence of cement, dust, and varying temperatures and loads. Product features: Material: NBR Compatibility: Gearboxes used in concrete mixers Resistance: High resistance to wear and aggressive working environment Sealing: Lip oil seal made of oil and temperature resistant elastomer Function: Prevents oil leaks and the penetration of contaminants into the gearbox The seal is a key element in maintaining the durability and trouble-free operation of the drive gearbox that drives the rotation of the mixing tank. Popular manufacturers include: Bonfiglioli, ZF, Rexroth, RR Holland (Reggiana Riduttori). Technical parameters: Dimensions: 135x215x11.5/41.5 Model: BDFOF SLSFX7

Material

NBR (nitrile butadiene rubber)

  • Operating temperature-30 °C to +100 °C

Good with oils, fuels, water and compressed air. Not for brake fluid, solvents, strong acids or sunlight.

Chemical resistance
Can be usedDo not use
Mineral oil, grease and hydraulic oil (H, H-L, H-LP)Brake fluid (DOT 3, DOT 4, DOT 5.1): the ring swells quickly
Diesel, fuel oil, keroseneSunlight and open air (ozone): the rubber cracks
Petrol (gasoline), propane, butaneAcetone, MEK, ethyl acetate and similar solvents
Water and water-based liquids, up to +80 °CBenzene, toluene, trichloroethylene (aromatic and chlorinated solvents)
Compressed air, also with oil mistSynthetic ester oils and fire-resistant fluid HFD-R
Water-based fire-resistant hydraulic fluids (HFA, HFB, HFC)Strong (concentrated) acids, e.g. nitric and sulfuric, and strong oxidizers
Oil-and-water emulsionsSteam and hot water above +100 °C
Weak acids, alkalis and salt solutions, at room temperature
Use with cautionPetrol with a lot of bioethanol (E10, E85): better use FKM (Viton)

Shows low compression set within the recommended temperature range.
